In a library my calculated column calculates what date Monday is the week after a document is last Modified.
=Modified-WEEKDAY(Modified,2)+8
I also want to add the minutes and seconds (not the hours):
=Modified-WEEKDAY(Modified,2)+8&" "&TEXT(Modified,"mm:ss")
Unfortunately, I can't get it to work. I get '42856.4667361111 12:06' instead of the date and time (minus the hours). What am I doing wrong?!
